This collection of individual slides uses annotated diagrams, tables and photographs to provide an overview of topics related to geologic time. Created by Dr. Vincent J.M. Salters at Florida State University, the slides discuss topics such as the geologic time scale, relative and absolute dating methods, metamorphic processes and facies, unconformities and cross-cutting relationships, chronostratigraphy, sequence stratigraphy and more. Diagrams and charts do a good job of clearly illustrating the concepts. The slides would be most useful as visual aids in a lecture setting or as a study resource for students.
